Quantized MIMO: Channel Capacity and Spectrospatial Power Distribution
Abbas Khalili, Elza Erkip, Sundeep Rangan
Millimeter wave systems suffer from high power consumption and are constrained to use low resolution quantizers --digital to analog and analog to digital converters (DACs and ADCs)…
Optimal Single-User Interactive Beam Alignment with Feedback Delay
Abbas Khalili, Shahram Shahsavari, Mohammad A. Amir Khojastepour +1
Communication in Millimeter wave (mmWave) band relies on narrow beams due to directionality, high path loss, and shadowing. One can use beam alignment (BA) techniques to find and a…
Understanding Energy Efficiency and Interference Tolerance in Millimeter Wave Receivers
Panagiotis Skrimponis, Seongjoon Kang, Abbas Khalili +7
Power consumption is a key challenge in millimeter wave (mmWave) receiver front-ends, due to the need to support high dimensional antenna arrays at wide bandwidths. Recently, there…
